**Major change**: RockVerse data migrated to Zarr 3.0.
Added
- Version checks for main dependencies at module import time.
- VoxelImage class
- Now can handle complex floating-point data.
- ``VoxelImage.__setitem__`` implemented and is always MPI collective.
- General function to execute in MPI rank 0 and broadcast exceptions.
- Dual energy inversion
- Handles arbitrary PDFs for standard materials, not only Gaussian.
- Segmentation array is now optional.
Changed
- VoxelImage class
- No longer directly inherits from Zarr array. Zarr array attributes and
methods in the VoxelImage class are now only accessible through the
class attribute ``VoxelImage.zarray``. Old Python scripts will crash if
not updated.
- ``VoxelImage.collective_getitem`` is deprecated and has been removed.
``VoxelImage.__getitem__`` is now always MPI collective. For non-collective
get item, access ``VoxelImage.zarray`` instead. For non-collective set item,
set ``VoxelImage.zarray`` instead.
- ``VoxelImage.save`` is now ``VoxelImage.copy`` and can save a re-chunked
copy to any Zarr store.
- Restricted to 3D arrays for performance; other ndims coming soon.
- tqdm bars now output to stdout by default.
- Dual energy CT processing
- Fully remodeled to use Zarr 3. No backward compatibility with RockVerse
versions < 1.0.
- Removed mandatory Gaussian distributions for the CT attenuation at
standard materials. Now accepts arbitrary probability density functions.
